This keychain will make sure your iPhone is never running low on battery

Imagine this: you just ran out the door, hopped on the train to work and look down at your phone only to realize you're barely hitting a 20% charge. Oh, and the best part? Your phone charger is right where you left it -- resting on your bed stand. For many, this isn't just a scenario. If you're an avid iPhone user, chances are you've found yourself in the identical predicament (more than once).

Good news is that there's a pretty easy solution to ensure it never happens again. If the logic is you'll never leave the house without your keys, this device will make sure you'll never leave the house without your keys and your charger. That's because they're one in the same.

Native Union, the technology-meets-fashion brand that has dominated the online market, has created their visionary Key Cable. The device is a keychain set with concealed connectors, giving you access to any USB power outlet. It's ultra-compact, so you won't be fighting against any unwanted pocket bulge or taking over massive amounts of space in your wallet or purse. Plus it comes in a range of colors, including the nautical geometric design as seen above and also variations of pinks, greens, blues, and more.

At the end of the day, it's the easiest -- and coolest -- way to ensure your iPhone, Tablet and everything in-between is juiced up when you're on-the-go.
